Could you give me a Trigonometric problem about angles of elevation/depression?

Question

With solutions and answers please. Or you could link me to a website that has samples. Thenks for those who are interested.

Answer 1

Here's a couple you can try. Good luck.

Answer 2

Its straightforward algebra then trigonometry. See how. {2x/(a million-x^2)} + x = (2x + x-x^3)/(a million+x^2) = = (3x-x^3)/(a million+x^2), stunning? Then. a million- {2x/(a million-x^2)}x = a million - (2x^2)/(a million-x^2) = {(a million-x^2) - {2x^2)}/(a million-x^2), stunning? Now take the ratio and on RHS a million-x^2 cancells. Now use x = tan@ as you needed. Then tan2@ = {2x/(a million-x^2)} isn't it a relaxing to have sound algebraic understanding in Trig?
